Setting a street 1125R up to drag race

[Puzzled]

Complete carbon fiber airbox, 2lb 8oz

 

[Puzzled]

Stock airbox 6lb 10oz, a 4lb 2oz difference in weight.

 

[Puzzled]

EBR Battery 2lb 2oz vs. stock 11lb 6oz, a 9lb 4oz weight savings.

 

[Puzzled]

I'll be changing the stock 8 piston for the previous generation 6 piston.

 

[Buell_Cru]

What a great write up. I can't wait to see the new numbers on it.

 

[Puzzled]

Stock fairing 2.10, race part 1.4 pounds, a 1.6 pound weight savings.

The rods are complete! Waiting on the pistons and rings still. The heads are on their way to be ported as well as the cylinders are en-route to get bored.

I have my contact info for Cometic to get my gaskets. I have a call into ARP for head bolts. The next thing is cams, I have multiple calls into EBR with not a single return call so I'm going to contact a cam company I know that has already cut some Rotax cams.

Once I get the rods and pistons I can balance the rotating assembly and start assembling. I still lack an exhaust but have made some calls to see what I can come up with. While I know I need a good exhaust I'm not to worried about it as an off the shelf complete system will be better than what I currently have.

Received an email the other day that the rods and pistons are done. Now its time for me to split the cases and get the crank ready to balance. The heads and cylinders should be at their locations Monday. The cylinders are going to take 2 weeks according to Millenium and I'd guess the heads will take just as long if not longer.

I spoke with Dan from Crower Performance (Son of Crower Cams) today. He was excited to work on a drag bike project as to date it has all been street and road race stuff for him. I boxed my cam cores up and they are off to him tomorrow. Once he receives them he'll give me a call and we'll discuss what the 1250 will like cam wise.

It looks like I'm down to gaskets, seals, bearings etc. and head studs as far as the hard parts go. Assembly and tuning will be a joy. The local guys don't want to touch the race ECM so I may have to take a run to EBR in Wisconsin to get this thing tuned. It sure is a little hard to believe someone closer can't tune using the EBR Race tuner. The local guys want to install Power Commander crap, I don't think so!

I split the motor cases today as I needed the crank to send off for balancing.

Here are the new rods, pistons and crank ready to go for balancing.

 

[Puzzled]

Look at the crap in the oil screen. I wonder how much was from the first time around and the dealer didn't clean it.

 

[Puzzled]

Stuff everywhere!

Old rods and piston. The damaged piston Erik Buell signed for me and sits on my desk.

Pretty stout clutch assembly.

 

[Puzzled]

I'm keeping it moving.

The rotating assembly was dropped off for balancing this morning.

This afternoon I ordered my head gaskets from Ashley at Cometic. I had to go with copper gaskets due to the bore size as the multi layer gaskets didn't have enough room for the crush ring.

I was finally able to order some parts from EBR. I ordered a set of ARP head studs as they stock them.

Aside from assembly I'm down to ordering a race exhaust system.

Somebody go check on Puzzled, he hasn't updated this thread in over an hour. [confused]

 

[Loki]

Lol nitto.

Look at that tummy!

Cool thread puzzled.

 

[Puzzled]

LOL

My cylinders came in today along with the ARP bolts and Buell gasket kit. I'll get some pics tomorrow of the cylinders. Millenium did a very nice job from the looks.

 

[03Firebolt9R]

Lmfao at Nitto. But I have been drinking. [cool]

 

[Puzzled]

The cylinders arrived from Millenium. They sure look like they do nice work. The cylinders were taken out to 4.275 which will net me a 1250 CC displacement.

 

[Puzzled]

ARP head studs, nothing fancy to look at but an important piece to keeping it all together.

 

[Puzzled]

Gaskets....

The complete gasket kit is a Buell part number that I picked up from ST. Paul HD. The head gaskets are from Cometic. As you can see they are copper. I ordered two different sizes as I wasn't exactly sure what I will need. Since there is very little gasket surface from the cylinder to the cam chain chest I'm going to O-ring the heads to help insure the seal. Originally I was going to O-ring the cylinder however that would be cutting into an already thin wall. So the heads make more sense (my first drag car motor was done this way).

 

[Puzzled]

Tools.....

I ordered the two 1125 specific tools listed on the EBR web site. One is a cam locking tool and the other is a crank locking tool. I also found a piston pin clip tool specific for the 1125 motor.
